2.6 Cooling System
The engine fan draws cooling air through the openings
in the sides and end near the battery. The alternator
fan draws cooling air through openings on the side
walls of the enclosure. The cooling air mixes with the
engine exhaust and is discharged at the exhaust
outlet. See Figure 2-10. To prevent generator set
damage caused by overheating, keep the housing
cooling inlets and outlets clean and unobstructed at all
times.
Note: Do not block the generator set cooling air inlets
or mount other equipment near or above them.
Overheating and severe generator damage may
occur.

2.7 Exhaust System
Remove all combustible materials from the exhaust
location. Combustible materials include building
materials as well as natural surroundings. Keep dry
field grass, foliage, and combustible landscaping
material a minimum of 1.5 m (5 ft.) from the exhaust
outlet.
Periodically inspect the exhaust system components
for cracks, leaks, and corrosion.
• Check for corroded or broken metal parts and
replace them as needed.
• Check that the exhaust outlet is clear.
2.8 Stepper Motor Coupling
Replace the stepper motor coupling and bushings at
the intervals shown in the service schedule. See the
Parts Catalog for replacement part numbers.
Figure 2-11 shows the location of the coupling
assembly under the air cleaner. Loosen the set screw
to remove the coupling from the motor shaft.
